The Sonoma County Trails Challenge is an invitation to discover your Regional Parks.
The Trails Challenge runs each summer and invites you to hike, run, bike or ride at least five trails featured in the free Trails Challenge guidebook. The guidebook includes park notes, trail ratings, turn-by-turn directions, maps, and suggestions for themed hikes.
Finishers get a free Trails Challenge T-shirt (while supplies last) and also could win park memberships and REI trail gear for sharing your #SonomaCountyParks #TrailsChallenge photos.
The 2019 guidebook will be published in early June. In the meantime, you're invited to download the 2018 guide(PDF: 4.63 MB) and keep it as a resource for exploring the parks.
